Cubs Designate Robert Coello For Assignment

The Cubs announced that they designated Robert Coello for assignment to create 40-man roster space for Rodrigo Lopez. The Cubs optioned Justin Berg to Triple-A to create 25-man roster space for Lopez, who was acquired from Atlanta yesterday and will be in uniform for Chicago today.

Coello, 26, appeared in six games for the Red Sox last year before Boston traded him to Chicago for Tony Thomas this February. In 48 1/3 innings at Triple-A Iowa, Coello has a 7.82 ERA with 7.6 K/9 and 4.5 BB/9. The 6'5" right-hander has a 3.78 ERA with 10.1 K/9 and 4.1 BB/9 in 127 minor league appearances, most of which have come in relief.
